After scouring every possible location I managed to find and restore a backup from this past January. This is one MAMMOTH whopper of an archive: over 1.6 million files taking up almost 100 gigabytes of space.
I am a lot more confident now that I will be able to restore the greater portion of everyone's records over the weekend.
I think the ebay sniper is working too but use with caution as I haven't tried any bids yet.
More updates to come!
